The base plate 47 is seated'u on the top of the shelf 16 as illustrated in *igure 6. Mounted on the base plate 47 is an adjusting screw 48 which' projects downwardly through a threaded opening in the base plate 47 and contacts with the upper surface of the shelf 16 to afford an arrangement wherebythe ink pot and the ink transfer mechanisms may be raised and lowered with respect to the upright frames 14 and 15.

The crank arm 43 is integrally formed on a rocker bracket 49 having bearing sleeves integrally formed thereon. The rocker bracket sleeves are rotatably engaged on the shaft 34. Formed on the upper edge of the rocker bracket 49 are a pair of beariiif yokes 50 in which a shaft 51 is journaled. ounted on the shaft 51 between the bearing yokes 50, is an ink transfer or carrier roll 52 which is adapted at predetermined times to have rolling contact with the ink supply roller 24 to receive a supply of ink therefrom. At selected intervals the control cam 41 acting on the roller 42 serves to rock the rocker bracket 49 so that the ink transfer roll 52 is swung cured on the opposite end of the shaft 54 to the outside of the bracket plate 17, is an inclined cam disc 56 which is in coacting relation with a beveled cam roller 57. The cam roller 57 is rotatably supported on a stub shaft 58 projectin from the outer face of the bracket plate 17 Also coacting with the cam roller 57 is an inclined cam disc 59 which is mounted on one projecting end of a shaft 60. The shaft 60 is slidably journaled in suitable bearings provided on the bracket plates 17 and 18, and carries another lntermediate steel roller 61. Mounted above the two steel rollers 53 and 61, and in rolling contact therewith, is a composition inking roller 62 which is supported on a shaft 63, the ends of which are 'ournaled in a pair of adjustable bearing brackets 64 mounted on projections 65 formed on the .upper margins of the bracket plates 17 and 18. Each of the bearing brackets 64 is provided with a pair of adto be raised and lowered with respect to the bracket plate projections 65.

Mounted on one projecting end of the shiftable' shaft 60 adjacent the outer side of the bracket plate 18 is a gear 67 (Fig. 3). The gears 55 and 67 are shiftable with the shafts and 'mesh with an intermediate gear 68. I The gear68 is mounted on one end of the shaft 39, and is driven by a large gear 69 which is supported on the shaft 11 to the inside of the upright bracket 15.

A composition ink supplying roller 70 has rolling contact with the intermediate ink transfer roller 61 and is mounted on a shaft 71, the ends of which are journaled: in a hanger bracket 72 pivotally supported on ashaft 73 journaled in bearing extensions 74 formed on the bracket plates 17 and 18. The hanger bracket 72 is provided with upwardly projecting inclined arms 75 each of which carries an adjusting screw 76. The adjusting screws are adapted to coact with the edges of the bracket plates 17 and 18 to permit adjustment of the ink applying roller 70. The ink applying roller 70 is adapted to apply .ink to a printing plate 77 which is mounted in a recess in the periphery of a 78 mounted on the shaft 11.

The printing plate 77 is adapted with each revolution of the printing roller 78 to print the type set-up carried thereon upon one surface of an intermittently advancing strip of paper 79 which is received from any suitable source of supply located at a convenient position above the machine. The strip of paper 79 is conducted downwardly around the outer side of an upper guide roller 80- mountedon a shaft 81 journaled in apair of upper bearing sleeves 82 formed on the upper edge of the upright frames 14 and 15. Mounted on the shaft 81 adjacent the inner side of one of the bearing sleeves 82 is'a gear 83 which 1 'the outer face of the cross plate 106 is a die is in mesh with. a gear 84 mounted on a shaft 85 whichis journaled in bearing sleeves 86 also formed on the upright frames 14 and 15.

Mounted on the shaft 85 between the upright frames 14 and 15 is a feed roller 87 around the inner side of which the strip of paper 79 is conducted. Positioned adjacent the inner side of the feed roller 87 is an auxiliary feed roller 88'which is supported on a shaft 89, the ends of which are journaled in adjustable bearing blocks 90. The bearing blocks 90 are slidable in guide grooves 91 afforded by yokes 92 formed horizontally in the upper portions of the upright frames 14 and 15. Closure blocks 93 carry adjusting screws 94 for adjusting the compression of springs 95 positioned between the bearing blocks 90 and the closure blocks 93. The stripof material 79 passes downwardly between the feed rollers 87 and 88, and then passes between the printing roller 78 and an auxiliary printing roller 95 which forms a backing or support for the strip of material when engaged by the printing plate 77. The auxiliary printing roller 95 is supported on a shaft 96 which is journaled in bearings '97 formed on.the upright frames 14 and 15. Mounted on the shaft 85 adjacent the inner side of the up-' right frame 15 is a gear 98 which receives a drive from a pinion 99. The pinion 99 is printing roller side of the upright frame 14 is a Geneva gear 104 which coacts with and is intermittently operated by a second Geneva gear 105 mounted on the shaft 11 adjacent the outer side of the upright frame 14. It will thus be noted that the shaft 11 is adapted to be continuously rotated, while the material feed shaft 96 is intermittently operated to cause the material 79 to be intermittently advanced through the field of operation of the rotatable printing plate 7 7. The set-up carried by the printing plate 77 is thus adapted to be printed at Spaced intervals along the strip of material.

After the strip of material is printed, said material is intermittently advanced through the field of operation of a cap blank punch and forming mechanism which will now be described.

Supported across the front of the machine by the upright frames 14 and 15, is a cross plate 106 provided with an aperture through which a punch sleeve 107 is adapted to be projected. Secured on the back of the plate 106 is a punch housing or sleeve 108 in which the punch sleeve 107 operates. Mounted on plate 109 which is provided with a punch receiving recess 110 which registers with the opening in plate 106. A diametric groove is provided between the plate 106 and the die plate 109 to permit the strip of lmaterial 79 to pass downwardlybetween the plates 106 and 109 to permit blanks to be punched from the material with each of said blanks having onesurface thereof printed according to the set-up provided on the printing plate 77.

Integrally formed within the die plate 109 is a circular rib or flange 111 which affords a restricted passage through which a punched cap blank is adapted to be forced by means of a cap forming plunger 112 which is slidably disposed within the punch sleeve'107. Removably engaged in a recess 113 formed in the outer face of the die plate 109 is one end of'a'c ap receivlng carton 114 which is supported on a bracket 115 secured to a front plate 116 fastened to the lower front edges of the upright frames 14 and 15. Formed on the-inner end of the forming plunger 112 is a shank 117 of reduced diameter, having formed on the outer. end thereof a pair of spaced lugs 118 (Fig. 5), which support a pin 119'0n which a link 120v is pivotally engaged. A pin 121 projects through the outer end of the link 120 and has pivotally supported thereon the forked end of a bell-crank arm 122, the upper end of which is integrally formed on a bell-crank sleeve 123, which is rotatably mounted on a shaft 124 journaled in brackets 125 formed on the upright frames 14 and 15. Also inte rally formed on the bell-crank sleeve 123 is a bell-crank arm 126 on the outer end of which a roller 127 is rotatably supported. The roller 127 tracks in a cam groove 128 formed in one side of a positive return cam disc 129 secured on the shaft 11.

Also secured on the shaft 11 is a blank punch control cam 130 on the periphery of which a roller 131 tracks. The roller 131 is rotatably mounted on one end of a bell-crank arm 132 which is integrally formed on abellcrank sleeve 133 keyed on the shaft 124 adj acent one side of the bell-crank sleeve 123. Integrally formed on the bell-crank sleeve 133 is a second bell-crank arm 134. a

Keyed on the shaft 124 adjacent the opposite end of the bell-crank sleeve 123 is a crank-sleeve 135 having a crank-arm 136 integrally formed thereon. The lower ends of the crank-arms 134 and 136 carry pins 137,-

the inner ends of which are pivotally engaged in a pair of. parallel arms 138 which are integrally formed on opposite sides of a sleeve 139 secured in the outer end of the punch sleeve 107 and-surrounding the shank ortion 117 of the forming plunger 112.

oiled around the plunger shank 117 is a coil spring 140, one end of which seats against the inner end of the sleeve 139, while the other end seats against the inner end of the forming plunger 112 to resiliently hold said plunger in its normal retracted position in engagement with a stop ring or rib 141 which is integrally formed on the inner periphery of the punch sleeve 107 Normally, sleeve 107 and the cap forming plunger 112, are in the retracted positions illustrated in Figure 6, to one side of the strip of material 79 which passes downwardly between the punch supporting plate 106 and the die block 109. After cap blanks have been. punched from the strip of material 79, the perforated end of the material 79 passes downwardly between a pair of guide rollers142 which are rotatably supported on the frame bars 2. After leaving the guide rollers 142 the perforated strip of material is coiled around a core 143 supported on a shaft 144 journaled in suitable bearings on the lower cross-bars of the framework 1. The shaft 144 and the reel core 143 mounted thereon are removable so that the reel of waste material 145 may be removed from the machine when necessary.

Figures 11, 12 and 13 illustrate a modified form of an ink supply mechanism adapted to be used in combination with the printing and cap forming machine in place of the inking mechanism illustrated and described in connection with Figures 1 to 10, inclusive.

the punch In the modified form of the device the parts which are similar to those shown in Figures 1 to 10, inclusive, will be designated with corresponding reference numerals, and only the new parts will be identified by additional numerals. The modified form of inking attachment is adapted to be supported upon the shelf 16 and comprises a pair of brackets 146 provided with slots 147 (Figures 11 and 13), and with bearing sleeves 148. Journaled in the bearin sleeves 148 are stub shafts or pins 149 w ich project outwardly from side walls 150 mounted on the side margins of a supporting plate .151. vThe plate 151, together with the walls 150, afford a framework upon which the ink suppl mechanisms are adapted to be supporte The framework supporting the ink supply mechanisms is pivotally supported by the pins 149 and is adapted to be adjusted with respect to the brackets 146 by means of clamping screws 152 which project through the slots 147 in the brackets 146, and" have the inner ends thereof threaded into threaded openings provided in the walls 150. Also mounted on the plate '151 is a air of brackets 153 connected by means 0 an inclined cross plate 154. The adjusting screw 20 and inclined'wall 21 of the ink pot 22 are supported on the adjustable framework 150-151, as are also the various ink feed rollers and the mechanisms for operatin the same. These various parts are indicated by the same numerals used in connection with Figures 1 to,10, inclusive, so that ink from the ink pct 22 may be supplied to the various intermediate rollers and evenly distributed to the ink applying roller 7 0 which, in turn, acts to apply an even coating of ink to the printing plate 77.

The operation is as follows:

A reel of material supported above the 80 and then downwardly between the feed rollers 87 and 88, passing one side of the printing roller 95 and then continuing downwardly through the punch mechanism to be wound up on thereel core 143. The reel shaft 144 maybe connected to receive an intermittent drive from the intermittently rotated shaft 85 permitting the punched out material to be intermittently wound on the reel core each time the material is advanced a predetermined amount.

The machine is started by shifting the clutch 8 to cause a drive to be transmitted from the motor 4 to the spur gear 6, thereby causing rotation of the shaft 7 and the gears 9 and 10. Rotation of the large gear 10 rotates the main shaft 11 and the gear 69 thereon to cause rotation of the intermediate gears 68, which in turn rotates both of the smaller shiftable gears and 67 mounted on the shiftable shafts 54 and 60, respectively. The ink distributing rollers 53 and 61 are thus continuously rotated and alternately shifted back and forth due to the action of the cam discs 56 and 59 wh1ch are actuated by the cam roller 57.

The gear 68 rotates the cam shaft 39, there by causing the control cam 38 to act on the roller 37 to operate the bell-crank arm 36 and the bell-crank arm 33. The finger 45 formed on the bell-crank sleeve 44 is adapted to coact with the adjustable stop screw 48,

to limit the swing of the bell-crank arms 36 and 33. Operation of the bell-crank arm 33 actuates the link 32, thereby causing the bellcrank 29 to be rocked whereby the pawl 28 acting on the ratchet 27 causes the ink supply roller 24 to be rotated a predetermined amount in the ink-pot 22 with each livered by the roller 52 is evenly distributed over the peripheral surface of the roller 53. From the roller 53 ink is transmitted to the intermediate roller 62 and then to the shift,- able ink distributing roller 61, which in turn delivers a supply of ink to the ink applying roller 70 with which it has rolling, contact. The roller 70 is adapted to be adjusted with respect to the shiftable ink distributing roller 61 by means of the adjusting screw 76. Y

F Ink from the applying roller 7 O is adapte to be evenly applied to the type set-up carried on the printing plate 77 with each revolution of the printing roller 78.

As the material is advanced downwardly between the printing plate 77 and the printing roller 95, one surface of the strip of, material 79 has printed thereon a notation correspondmg to the set-up of the type carried on the printing plate. It will thus be noted that the intermittently advancing strip ofmaterial 79 is printed at spaced intervals and is intermittently advanced downwardly between, the punch supporting cross-plate 106 and the die block 109. When a printed section of the material is properly centered in the punch mechanism, the punch control cam 130 operates the'roller 131 and the crank-arm 132 causing the shaft 124 to be rocked, thereby causing the crank-arms 134 and 136 to be swung inwardly to operate the punch sleeve 107. The punch sleeve 107 coming into contact with the strip of material 79, punchesout a printed cap blank and then advances the blank towards the ring 111. With the advance of the punch sleeve 107, the ring 141 in said punch sleeve causes the forming plunger 112 to advance simultaneously with the punch sleeve. After a blank has been punched from the material the blank forming control cam 129 coacting with the roller 127 causes the crank-arm 126 to berocked upwardly, thereby causing the crank-arm 122 to be swung inwardly to actuate the connecting link 120, thereby causing the forming plunger 112 to be pushed outwardly be yond the end of the punch sleeve 107 to contact and force the cap blank through the forming ring 111, thereby. causing the margin of the blank to be bent over to form a rim or flange. 'The formed cap when leaving the forming ring 111 ispushed into a re ceiving'ca-rton 114 which is supported in place on the bracket 115, with one end of the carton engaged in the die block 109.

With each rotation of the shaft 111 a printed capblank is punched out of the strip of material and is forced through the forming ring and into; the cap receiving carton 114. The printed caps are seated one within the other within the carton until a predetermined number of caps have been delivered, after which the filled carton may be removed from the carton supporting bracket 115 and a new carton substituted in place thereof.

The modified form of inking mechanism illustrated in Figures 11 to 13, inclusive, is

adaptedto be operated from the machine in a manner similar to the inking mechanism illustrated in Figure 6. form of inking mechanism a novel arrangement is provided whereby the entire inking mechanism may the machine frame by merely releasing the clamping screws 152 and tilting or adjusting the framework 150-151 about the pins In the modified be adjusted with respect to 149, whereby the ink applying roll- 70 may be adjusted with respect to the print jng plate 77. After the pressure of the ink applying roll has been adjusted with respect to the printing plate and drumfthe clamping screws 152 are tightened to hold the inking mechanism supportingframework in a predetermined position of adjustment. The modified mounting for the inking mechanism affords an arrangement whereby the, entire 'inking unit may be conveniently adjusted with respect to the machine frame, and with respect to the printing drum, and furthermore, permits the inking unit to be conveniently mounted in place or removed as-a unit to permit replacement of parts or repairs when necessary. i v

I am aware that many changes may be made, and numerous details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted hereon, other- .wise than necessitated by the prior art.

I claim as my invention:
